Ship EKS logs

For Kubernetes, a DaemonSet ensures that some or all nodes run a copy of a pod.
This implementation is uses a Fluentd DaemonSet to collect Kubernetes logs.
Fluentd is flexible enough and has the proper plugins to distribute logs to different third parties such as Logz.io.

The logzio-k8s image comes pre-configured for Fluentd to gather all logs from the Kubernetes node environment and append the proper metadata to the logs.
